STOVE ATTACHMENT.

Application filed July 19,1907. Serial No- 384,525.

found that this air has a tendency to seek and rise through the center of the body of fuel thus bringing about a comparatively fierce combustion at the center of the fuel and leaving the periphery of the body of fuel comparatively dead. It is quite common to fiute the interior of the fire-pots with a view to providing channels for air for combustion to move up from the ash-pit around the fuel so as to enhance combustion at the periphery of the top of the fuel bed. In addition to this various expedients have been contrived for delivering air of combustion downwardly upon the periphery of the fuel bed, but the constructions have generally been of a more or less complicated or ob structive character and have often called for special designs of stoves in order to permit of their presence.

My present invention has reference to a construction readily adapted for ordinary types of heating stoves, and quite free from the charge of unduly obstructing the interior of the stove.

My invention will be readily understood from the following description taken in connection with the accompanying drawing in which:

Figure 1 is a perspective view of a stove attachment embodying an exemplification of my invention: Fig. 2 a vertical section in the plane of line a of Fig. 1: Fig. 3 35 a vertical section in the plane of line b of Fig. 1: and Fig. 4 a vertical section in the plane of line 0 of Fig. 1. Fig. 1 is upon a smaller scale than the remaining figures of the drawing:

In the drawing:-1, indicates hollow segments adapted to fit within a stovebody at the top of the firepot: 2, the joint or gap between the contiguous ends of the segments, the separate segmental construction for the whole 01' partial ring thus formed being preferable to an integral ring 011 account of the facility 45 for manufacture and for inserting the structure in a stove, and on account of less liability to rupture by expansion and contraction: 3, lugs formed upon the segments to permit them to be bolted against the stove wall to hold them in place: 4, a series of nozzles projecting downwardly from the hollow segments in position to deliver air downwardly upon the fuel just within the wall of the fire-pot, the lower extremities of these nozzles being preferably carried a trifle inwardly and beveled somewhat so that the air discharged downwardly from them will be delivered also somewhat inwardly: 5, a pair of upwardly presenting sockets on the tops of the segments, these sockets communieating with the hollow of the segments and being far separated from each other: 6, a horizontal jointless curved air-chamber adapted to lie within the front portion of the wall of the stove-body above the fire door thereof, the length of this chamber being equal to the distance between the sockets 5: 7, a downwardly presenting socket at each end of the chamber 6, in vertical line with the sockets 5: 8, an open-fronted enlargement at the center of length of chamber 6: 9, lugs carried by the chamber 6 to permit it to be secured, by means of screws, against the inner surface of the stovebody above the fire-door thereof and permit the open front of the enlargement to present itself at a suitable hole formed in the stove-body over the fire-door: 10, a register cooperating with the open front of the enlargement and adapted to be operated exterior to the stove-body to which the horizontal pipe is attached: and 11, a pair of vertical tubes properly jointed into the sockets of the segments and the horizontal chamber and placing the register opening in communication with the nozzles 4.

The structure having been secured within a stovebody, the suction caused by the draft of the stove causes the air to be drawn in at the register and jetted out of the nozzles and into the periphery of the fuel bed, the air for combustion thus supplied to the periph ery of the fuel bed being highly heated by reason of its passage through the chamber, hot pipes and the segments. When the fire is to be banked thenfin addition to shutting off the ordinary drafts, the register 10 will control the exact volume of air that the attachment delivers to the fuel, or it maybe shut entirely off. The device is practically air-tight at all points between the register and nozzles so that air delivered by the attachment is at all times under perfect control.

I claim:

1. A stove attachment comprising a hollow structure adapted for attachment to a stove body at the top of its fire-pot and formed with a series of nozzles adapted to jet air downwardly upon the periphery of the fuel bed in the fire-pot and having upwardly presenting tube connections, a pair of tubes extending upwardly from said tube connections and adapted to straddle the firedoor of the stove and to extend above the door, a horizontal chamberstructure adapted to be secured to the stove-body above the fire-door and having its ends connected with the upper ends of said tubes and having an open-fronted inlet between its ends, and a register at said inlet, combined substantially as set forth.

2. A stove attachment comprising a hollow structure adapted for attachment to a stove body at the top of its fire-pot and formed with a series of nozzles adapted to jet air downwardly at an inward inclination upon the periphery of the fuel bed in the fire-pot and having upwardly presenting tube connections, a pair of tubes extending'upwardly from said tube connections and adapted to straddle the fire-door of the stove and to extend above the door, a

horizontal chamber-structure adapted to be secured to the stove-body above the fire-door and having its ends connected with the upper ends of said tubes and having an opemfronted inlet between its ends and a register at said inlet, combined substantially as set forth.

A stove attachment comprising a plurality of hollow segments adapted for attachment to a stove body at the top of its fire-pot and formed with a series of nozzles adapted to jet air downwardly upon the periphery of the fuel bed in the fire -p0t and having upwardly presenting tube connections, a pair of tubes extending upwardly from said tube connections and adapted to straddle the tiredoor of the stove and to extend above the door, a horizontal chamber-structure adapted to be secured to the stove-body above the fire-door and having its ends connected with the upper ends of said tubes and having an open-fronted inlet between its ends, and a register at said inlet, combined substantially as set forth.
